Basicly i bought a turbo off ebay a few months back that said it was for an s3 on arrival i inspected the turbo and noticed that the boost outlet had been modified it looks about 4inches longer than it should be also it has a 4 bolt exhaust outlet dose this sound right all the other k04's ive...

Hi sorry if this has been asked a thousand times before , ive had a search around but cant seem to find the answer ! does a ko4 turbo fit directly onto the stock exhaust manifold ? thnaks james by the ways the cars a mk3 ibza cupra

Im new to this site and want bit of info on mk3 ibiza want bit more power so thinking of adding a turbo ive read up on k03s and k04 could someone point me in right direction of which one to get and what donor cars i can get them from? is k04 straight bolt on? which is better etc?

just stumbled on this. :think:

im not sure if this is in the right section but an wondering if the turbo used in the mk2 leon tfsi would fit into i mk 1 cupra r. im sure there both k04 turbos but is there much difference to fittings an would it give it more power or would it be no good for the leon mk1. thanks for any input

Hello, Currently doing a K04 conversion into a mk4 golf. Got all my bits but have a DP question. I have a downpipe that has been made from a leon cupra r downpipe. Its been welded into one complete 2.25" pipe, instead of the usual twin pipe setup. Looks like the pipe is 3" then reduces...

i dont know if im being daft, i have little knowledge on turbos and what it takes to fit them, but ive had a browse on the internet today about k04 turbos on an ibiza. i came across k04 manifolds at 250ish quid. i was under the impression they'd cost more than this. i can post links if needed...

Hi Just wanted your thoughts on the K04 hybrids that are out there i have seen alot of happy people with them but how do the company's compare on performance? I haven't seen the spec on JBS K05 or backdrafths hybrid K04 But have seen the Turbo Dynamics info: MD421 Modified compressor...

Found this the other day, In stock at TSR apparently at 650quid! Looks nice, the young lad didn't have much to say about it though, no power gains or anything they said they have a customer running round with one on at the moment. What you guys think? I think under bonnet temps could be an issue?

Doing a k04 upgrade on a 1.8T. I've purchased some tasty new hitachi boltdown coilpacks as i understand the existing ones will most probably fail after the conversion. 2 questions- 1) I've not installed the new turbo yet (will do next week) and i reckon i've currently got one coilpack...

Not specifically Leon related so i suppose it shouldn't be posted in here but question is, what cars in the VAG range use the same engines and turbos? (New breed) I know the base 2.0t cars are 200bhp, although the new golf gti upto 210bhp? What have VW done to extract the additional 10bhp...

Hello all, i had my lcr remapped last month, fun but getting bored already, haha, i was looking to go for the hybrid option, what companies are the best and roughly how much doe it all cost? thanks alot james

Ive plumbed my k04 turbo in, oil feed, oil return, water in, water out... now on the back of the turbo ive found a threaded hole with a tiny hole in the back of it, cant see where it goes to but i took a photo so you could see... as i understood there were only 4 lines to and from the turbo so...

to cut a long story short i got a k04 ibiza, got a n75j fitted, overboost 14psi tailling off to 10 or 11, i'm not happy with this so i bought a mbc to try, swapped it for the n75 but keeping the valve plugged in i get overboost 23psi tails off to about 16psi but hit limp mode sometimes, if i...

looking for a uprated manifold, tubular equal length is there one that does not reposition the turbo, as i dont want to have to change my custom downpipe unless i have to, so looking for bolt on bolt off job. seen a few tig art ones on ebay that are ceramic coated they look awsome but need...

Today I spoke to a company that refurb and upgrade turbos and they reckon that they can refurb the K04 Cupra turbo and include a new thrust bearing for better reliability and shorten the shaft and modify the fins for better spool and top end power through ability to run slightly higher boost...
